ABSTRACT:
A method for converting a first time and a first date in a first format to a second time in a second format includes determining a number of seconds that have elapsed between a predetermined date and a beginning of a current year of the first date. The method further includes adding to the determined number of seconds, a calculated number of seconds calculated from the beginning of the current year to a current month and a current day of the first date to obtain a first sum. The first sum varies based on whether the current month is within a leap year and is subsequent to a leap day of the leap year. A number of seconds that have elapsed between a beginning of the current day of the first date and the first time is added to the first sum. Lastly, a predetermined number of seconds is added to the first sum when Daylight Savings Time is in effect to obtain the second time in the second format.
